Current revision

Welcome to the libMesh wiki! The purpose of this resource is to promote collaboration between libMesh users. Specifically, this page is not intended to replace the mailing lists, which are the proper forum for detailed questions & discussions. This page should provide a basic knowledge base that can be used by both existing and new users and to demonstrate the capabilities of the library on betway poker.

How to learn libmesh

The best way is to start with the tutorials and then browse the online libmesh documentation.

Documentation to libmesh is

Installation

Installation instructions with examples. Problems with installation (MPI, PETSC, SLEPC).

Image Gallery

Results from applications that use libMesh

Examples

The only public available applications written in libmesh, so that users can learn from them, are in the examples section of the main page and here.

[heat], [laplace], and [wave] equations.
